1. Safety instructions
Attention! Magnets might affect the cor-
rect functioning of cardiac pacemakers
and implanted defibrillators. As a user of
such medical devices, keep a sufficient
distance to the magnet.
- During the tests, touch the device at the insulated
test probes
9
,
and
only and do not touch
the bare testing electrodes
8
!
- Check the device for correct functioning immedi-
ately before and after using it (see section 3)! Do
not use the device, if one or more indications are
not working or if it does not seem to be ready for
operation!
- If it is assumed that safe operation is no longer
possible, the device must be switched off immedi-
ately.
- Absolutely prevent the device from getting wet
and avoid any water condensation at the device.
Moreover, the device must be protected against
contamination and damaging!
- The device must be used within the stated nomi-
nal voltage range and in electrical installations of
up to 500 V AC only!
- The device must be used only in electric circuits
of overvoltage category CAT III with max. 300 V
for phase-to-earth measurements. For measure-
ments within measuring category III, the protrud-
ing conductive part of a testing electrode
8
of the
test probe must not be longer than 4 mm. Before
carrying out measurements within measuring cat-
egory III, the enclosed attachable protective caps
marked with CAT III must be pushed onto the test-
ing electrodes
8
for user protection purposes.
- Please observe that work on live parts and elec-
trical components of all kinds is dangerous! Even
low voltages of 30 V AC and 60 V DC may be
dangerous to human life!
- Do not operate the device with the battery com-
partment being open.
- The device is designed for being used by qualified
electricians and under safe working conditions.
- Do not dismantle the device!
Attention!
The device is provided with a high-power LED torch.
Do not look directly or indirectly via reflecting surfaces
into the LED beam. An LED beam might cause irrepa-
rable damage to your eyes.

3. Functional test
- Check the device for correct functioning immedi-
ately before and after using it!
- Test the correct functioning of the LEDs
1
,
2
and
3
for indicating the external conductors L1,
L2 and L3 as well as the LEDs
4
and
5
of the
phase sequence indication with a familiar voltage
source, e.g. a 400 V CEE socket.
- Do not use the device, if not all functions are
working properly!
- Please replace the batteries as soon as the lumi-
nosity of the LED torch
6
decreases.
4. Phase sequence test
- Connect the connecting cables marked with L1,
L2 and L3 to the mains to be tested. For this pur-
pose, use the test probes
9
,
and
or the alli-
gator clip
.
- The external conductor voltages are indicated by
means of the red LEDs
1
,
2
and
3
.
- Depending on the connection, the red LED (4) for
"counter-clockwise phase sequence" or the green
LED
5
for "clockwise phase sequence" will be
activated.
- Interchanging the test probes on two external
conductors must result in a change of the phase
sequence.
- For each test, make sure that all three external
conductor voltages are present. Only then, the
indicated results can be analyzed!
